To provide an article return device.SOLUTION: The article return device includes: a vehicle traveling along a traveling rail installed on the ceiling; a hoist module connected to the vehicle for transferring articles; a step measuring section that measures the step of the traveling rail by measuring the distance value to the traveling surface of the traveling rail respectively by the first displacement sensor and the second displacement sensor, which are provided on the vehicle and positioned along the traveling direction being separated from each other with a predetermined space therebetween; and a control section that determines whether the traveling rail is stepped or not by correcting an error between a first measured value of the first displacement sensor and a second measured value of the second displacement sensor due to the inclination of the vehicle.SELECTED DRAWING: Figure 3
【課題】物品返送装置を提供する。【解決手段】物品返送装置は、天井に設置された走行レールに沿って走行するビークルと、前記ビークルに連結され、物品移送のためのホイストモジュールと、前記ビークルに設置され、走行方向に沿って所定間隔で離隔されて配置された第1変位センサーと第2変位センサーが前記走行レールの走行面までの距離値をそれぞれ計測して前記走行レールの段差を測定する段差測定部と、及び前記ビークルの傾きによる前記第1変位センサーの第1測定値と前記第2変位センサーの第2測定値に対する誤差を補正して前記走行レールの段差如何を判別する制御部を含むことができる。【選択図】図3
